Re: [platform-swt-dev] mozilla interfaces and swt.browser widget

Hi Vladimir,

(note that swt usage questions like
this should be asked on the eclipse.platform.swt newsgroup, not this mailing
list)

XPCOM error 0x80004002 is NS_NO_INTERFACE,
so your line that's failing seems to have an error.  I don't think
that using nsIAccessNode is necessary, the snippet below works for me:

nsIWebBrowser webBrowser = (nsIWebBrowser)
browser.getWebBrowser();
nsIDOMDocument document = webBrowser.getContentDOMWindow().getDocument();
nsIDOMHTMLDocument htmlDocument = (nsIDOMHTMLDocument)document.queryInterface(nsIDOMHTMLDocument.NS_IDOMHTMLDOCUMENT_IID);
nsIDOMHTMLElement element = htmlDocument.getBody();
nsIDOMNSHTMLElement nsHtmlElement =
(nsIDOMNSHTMLElement)element.queryInterface(nsIDOMNSHTMLElement.NS_IDOMNSHTMLELEMENT_IID);
String bodyContent = nsHtmlElement.getInnerHTML();

Subject	[platform-swt-dev] mozilla interfaces and swt.browser widget

Hello, all!

I am trying to get the content of document.body element in SWT.BROWSER
widget
According http://www.xulplanet.com/references/xpcomref I wrote such code
(this is the most
relevant part):

...

Browser browser = new Browser(shell, SWT.MOZILLA);
nsIWebBrowser webBrowser = (nsIWebBrowser) browser.getWebBrowser();
nsIDOMNSDocument nsHtmlDocument = (nsIDOMNSHTMLDocument)webBrowser.getContentDOMWindow().
                    
    getDocument().queryInterface(nsIDOMNSHTMLDocument.
                NS_IDOMNSHTMLDOCUMENT_IID);
nsIDOMHTMLBodyElement body = (nsIDOMHTMLBodyElement) htmlDocument.
                   getBody().queryInterface(
                    
      nsIDOMHTMLBodyElement.
                    
      NS_IDOMHTMLBODYELEMENT_IID);
nsIAccessNode accessNode = (nsIAccessNode)body.queryInterface(nsIAccessNode.NS_IACCESSNODE_IID);
String bodyContent = accessNode.getInnerHTML();
...

But while querying nsIAccessNode interface i get an exception
org.mozilla.xpcom.XPCOMException: The function "QueryInterface"
returned an error condition  
(0x80004002)
Whether my approach is incorrect or problem consist in internal realization
of swt.browser?

Thank in advance
